Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for removal from the CWA section 303(d) List under section 4.3 of the Listing Policy. Under this section a single line of evidence is necessary to assess listing status.
9 lines of evidence are available in the administrative record to assess this pollutant. 2 of 104 samples exceeded the OBJECTIVE. 1 of 111 samples exceeded the OBJECTIVE. 0 of 111 samples exceeded the OBJECTIVE. 0 of 104 samples exceeded the OBJECTIVE. 0 of 0 samples exceeded the OBJECTIVE. 3 of 6 samples exceeded the OBJECTIVE. 15 of 137 samples exceeded the OBJECTIVE. 1 of 137 samples exceeded the OBJECTIVE. 0 of 130 samples exceeded the OBJECTIVE. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for removing this water segment-pollutant combination from the CWA section 303(d) List. This conclusion is based on the staff findings that: 1. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. 2 of 104, 1 of 111, 0 of 111, 0 of 104, 0 of 0, 3 of 6, 15 of 137, 1 of 137 and 0 of 130 samples exceeded the OBJECTIVE and this does not exceed the allowable frequency listed in Table 4.2 of the Listing Policy. 4. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are not met. |
Regional Board Decision Recommendation: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be removed from the section 303(d) list because applicable water quality standards for the pollutant are not being exceeded. |
State Board Review of Regional Board Conclusion and Recommendation: | |
State Board Decision Recommendation: | After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board. |

Regional Board Conclusion: | 303(d) listing decisions made prior to 2006 were not held in an assessment database and are not available in the administrative record.
There is sufficient justification to place it in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by USEPA, and is expected to result in attainment of the standard. This conclusion is based on the staff findings that: 1. The Santa Monica Bay DDT and PCB TMDL was approved by USEPA on 03/26/2012. 2. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met. |
Regional Board Decision Recommendation: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be removed from the section 303(d) list because applicable water quality standards for the pollutant are being exceeded. |
